Re: Pipeline Min/Max values

I suspect you are showing the Result Mesh and the Pipeline is empty. No, no it's not empty. The highest stress is in the root of the weld and not visible from this side - the design would need a modification, to releave it. If I turn the model around, you'll see a proper red spot colors.

Pipeline Min/Max values

Hello, I have yet another pipeline question. Since there's nothing in https://www.freecadweb.org/wiki/FEM_PostPipelineFromResult yet and couldn't find anything regarding this. When I get results, I select them and click " Post Pipeline from Results " and a "Pipeline" appears (well, that's a horrible...

Re: Multibody Part: Unknown C++ exeption when saving

Version: 0.17.13408 (Git) This is realthunder's fork? If so some of this may be different to FreeCAD master. Yep, that's right. I thought he actually introduced the new topology, so I was expecting that this part would be same or better from the main fork... I didn't and don't want to confuse anyon...

Re: Multibody Part: Unknown C++ exeption when saving

When using non-PartDesign WB tools on PartDesign objects you need to operate on the Body, not the Features inside the Body. It makes sense, but I didn't realized that. But once again, I found that in past empirically, but forgot about the difference. Preferably, it should be restricted or user shou...

Re: Multibody Part: Unknown C++ exeption when saving

To make multiple disconnected solids each must be created in it's own body. Fair enough. That is what I empirically discovered, so now I know it's correct. Another thing is that when trying to create multiple bodies, I get issues too. The warning would be enough for user to understand what is happe...

Re: Multibody Part: Unknown C++ exeption when saving

Another multibody issue: 1) I fusioned the new body with the previous body (COLUMN001) into Fusion object 2) Now I want to draw a rectangle on one of the face and make it a boolean fragment, so I select the face and click on Create sketch command. I get an error, that the object must be contained wi...

Re: Multibody Part: Unknown C++ exeption when saving

Independent of whether your workflow is correct, wrong, good or bad such an error shouldn't occur. Could you give step-by-step instruction how to get into this state, please? Maybe we could fix this then before the 0.17 release. OK, I'll do that, I'll put each issue I ran into and will be able to r...

Re: Multibody Part: Unknown C++ exeption when saving

OK, I found 1 workaround: To model the other part in a separate file and then copy&paste it into the target file. Then there are no troubles.

Multibody Part: Unknown C++ exeption when saving

Hello, this is related to development version 0.17 and it's new topology. Perhaps I am doing something incorrectly with my attempts of multibody part. The reason for a multibody part is, that I need to process it with FEM later and it should be easier to model it in one part, do a boolean fusion and...
